The Merge created quite a big imbalance between the amount of squads available to each faction (obviously, depending on how much you grinded them during the campaigns time and premium squads purchased).
For example, my numbers of squads (tank squads in the brackets)
USSR 91 (10)
USA 82 (9)
Germany 130 (16)
Japan 40 (3)
This leads not only to Japan suffering (due to never having more than one campaign) in terms of BR presets flexibility (you don’t have 5 assaulter or 5 engineer squads to have one per each BR preset), but most glaringly it effects vehicle rotation capabilities.
For instance:
With Germany I can play Tiger II H → Tiger II P → Panther because I have lots of squads
With USA I can play 2 high BR tanks because I have a squad with Jumbo Sherman and a squad with Pershing/Super Pershing
With Japan I can only play 1 high BR tank, because the other two squads only contain BR 1-3 tanks
Suggestion 1: add an event tanker squad without vehicle limitations for each nation
You could just go through each soldier and give them BR-appropriate gear each, you know.
Same soldiers, swappable guns.
This suggestion seems less like an answer to a problem and more like laziness of having to go through each soldier one by one.
At that point you should just be advocating for improved presets that would switch the entire roster to a higher or lower BR preset than asking for a vehicle squad that can use every existing vehicle so you won’t have to swap them out.
I think this will really affect the gaming experience.
Especially considering that the current replacement mechanism is not perfect.
Sometimes you even have to manually replace weapons that are not fully upgraded or are forced to buy duplicate items.
